I'm thinking about swapping out a 12V-2x6 GPU power cable in my computer, but I'm concerned about the humidity level in my room, which is around 34%. Since I don't have an anti-static wrist strap, I'm wondering if it's safe to proceed. I can't increase the humidity, and it's cold and dry because it's winter where I am. If I touch the metal of the case to ground myself before I start, is the risk of static electricity (ESD) low enough to go ahead? Also, I'll be standing on carpet and was considering putting down cardboard and working barefoot for extra safety. I just want to make sure that this expensive GPU doesn't get damaged during the process, as I tend to get really anxious about things like this. Any advice would be appreciated!

Keep your original PSU plugged in to a grounded outlet, and flip the switch to off before you start working. Touch an unpainted part of the case to ground yourself at the beginning and while you work. Also, anti-static wrist straps are really cheap and can give you extra peace of mind if you pick one up.
Do you often get static shocks from touching doorknobs or furniture? If not, then you’re probably okay. Just make sure to lift your feet instead of shuffling on the carpet. And remember to ground yourself by tapping a metal part of your case before you touch any components.
You can ground yourself by keeping the PSU plugged into power but switched off while you touch the case. Just keep contacting the case as you work on changing the cable. In general, replacing a PSU cable shouldn’t be a huge ESD concern, especially now with modern components being more resistant than before.
When swapping the cable, try to only touch the plastic connectors. If you avoid touching any metal parts, you should be fine. Just be careful when you do need to touch anything conductive; that's where ESD can come into play.
